Theinner Figure 12 is a plan view illustrating the blank ends of thesupporting bars are disposed over n 'from which the modifiedform ofelevator is conthe outer edges of the window sill while the structed.outer ends of the supportingV bars terminate a Figure 13 is a sideelevation illustrating a Winsubstantial distance from the window sill to`sup- 110 port the side members 2 of the seat frame a considerabledistance beyond the Window sill.

Elevators 19 are adjustably secured to the supporting bars and rest uponthe Window sill as shown in Figure 1 and each includes a blank 20 bentto form plates 21 and 22 arranged angularly to each other and the plates2l and 22 have formed thereon plates 23 and 24 respectively and theyextend angularly to the plates 21 and 22 and are secured togetherforming a bottom to the elevator. The bottom is disposed on a slightinclination to rest evenly on the top surface of the window sill orframe as shown in Figure l. The plate 21 is provided with a slot 24 toreceive a bolt 25 carried by the respective supporting bar and onwhichis threaded a Wing nut 26 permitting the elevator to be adjustedvertically. The plate 21 has formed on one edge a rightangularlydisposed extension 27 tting in a vertical groove 28 formed in thesupporting bar. The side rail above the respective supporting bar isgrooved or channelled as shown at 29 to permit the upper end of theelevator to move therein When in one of its adjusted positions. It willbe seen that the elevators may be readily adjusted on the supportingbars so that the seat frame when resting upon the stool 8 may besupported in a horizontal positionfand cooperate with the bars andclamps in firmly anchoring the seat in position against accidentaldisplacement. The inner ends of the supporting bars are shaped to slantfrom the outside to the inside at approximately six degrecs less than atrightangles to conform to the plates 23 of the elevators 19. The innersurfaces of both the supporting bars and the elevators are shaped toapproximately six degrees less than at rightangles, so as to form thedesired contact with the sill to make this function of the assemblyeffective.

Referring to my modied form of elevators as shown in Figures 11 to 14,each consists of a blank 30 consisting of plates 31 and 32 bentangularly to each other and a right-angularly disposed extension 33 ofthe plate 31 fitting in the groove 28 of 4the respectivesupporting bar.Extensions 34 and 35 are formed on the plates 31 and 32 respectively andthe extension 35 forms the bottom wall of the' elevator. The plate 31 isslotted to receive the bolt 25 of the supporting bar. A window sillengaging element 36 of substantially T-shape is formed from a blank 37and the head portion is riveted or otherwise secured to the extensions34 and 35 of the elevator so that when applied to a window frame, thevertical portion 38 Will engage the outer vertical surface of the Windowsill while the horizontal portion 39 Will rest on the upper surface ofthe sill positioning the elevator outwardly of the Window frame.

The outer ends of the supporting bars 16 extend further from the centerof gravity of the seat than the inner ends to permit said outer ends tosustain a greater thrust Where required and thereby provide rigidity tothe rear of the seat.

The clamps 10 when in engagement with the `stool 8 prevents sidesway ortipping back out of the Window of the device by the operator. Thesupporting bars and their respective elevators alongr with the clampsaord a simple and efcient moans for locking the seat to members of theWindow frame and permit adjustment so that the seat will t differentWindow frames and allow the seat to be firmly set in place and cbviatingthe possibility of the seat becoming loose or moving from side to sideor from dropping back or out of the Window which would endanger thesafety of the operator.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination and arrangementrof parts may be made Without departing fromthe spirit and scope of my invention, as claimed.

Having thus described my invention, What I claim is:

A Window cleaners seat comprising horizonta supporting bars havingvertical guide grooves, a seat portion resting on said bars, meansconnecting said bars to the seat portion to permit the latter to beadjusted horizontally on said bars, elevators carried by the bars andeach including angularly related Walls to engage angular faces of aWindow sill, means adjustably connecting the elevators to the bars,flanges on said elevators and received by the guide grooves, and meanson the seat portion to engage the Window sill.
